Specifically, when the fixing ring 51 located at the upper side moves downward under the driving of the positioning device 8, the fixing ring 51 located at the upper side drives the connection ball 42 to move downward, so that the sealing component 43 in the inner cavity of the first sealing groove 421 is stressed, and a gap between the connection ball 42 and the second fixing tube 21 is sealed.
In order to avoid leakage of the petrochemical or other liquid from the sealing device 4 when the delivery pipe 1 delivers the petrochemical or other liquid, as shown in fig. 10, the sealing member 43 comprises a first sealing member 431 slidably connected to the inner wall of the first sealing groove 421, the lower end of the first sealing member 431 extends to the outside of the connecting ball 42, the lower end of the first sealing member 431 is fixedly connected to the upper end of the second fixing pipe 21, a second sealing member 432 slidably connected to the inner cavity surface of the first sealing groove 421 is arranged at the upper part of the first sealing member 431, and a spring 433 fixedly connected to the upper surface of the inner cavity of the first sealing groove 421 is arranged at the upper end of the second sealing member 432.
In order to match the second sealing member 432 to seal the gap between the connecting ball 42 and the second fixing tube 21, as shown in fig. 10-11, the first sealing member 431 includes a first supporting ring 4311 slidably connected to the inner cavity surface of the first sealing groove 421, the lower end of the first supporting ring 4311 is fixedly connected to the upper end of the second fixing tube 21, a sealing ring 4312 is disposed in the middle of the upper end of the first supporting ring 4311, and sealing holes 4313 are formed in an array on the inner side of the upper end of the sealing ring 4312.

Specifically, when the fixing ring 51 located at the upper side drives the connection ball 42 to move downwards, the sealing ring 4312 in the sealing member 431 at the upper end of the fixing tube two 21 enters the inner cavity of the sealing ring 4312 in the sealing member two 432, meanwhile, the sealing block 4322 enters the inner cavity of the sealing hole 4313, at this time, the sealing ball 41 and the connection ball 42 cannot rotate relatively any more, and after the upper end of the supporting ring one 4311 contacts with the lower end of the supporting ring two 4321, the fixing ring 51 located at the upper side continuously pushes the connection ball 42 to move downwards, so that the spring 433 is stressed to compress, and the force between the contact surfaces of the supporting ring one 4311 and the supporting ring two 4321 is increased, thereby achieving the sealing effect.
Further, when the measuring instrument 6 needs to be removed, the fixing ring 51 located at the upper side is driven to move upwards by the positioning device 8, so that the sealing blocks 4322 are not contacted with the surfaces of the inner cavities of the sealing holes 4313, at this time, the fixing ring 51 located at the upper side can be driven to rotate again by the rotation transmission device 7, and the measuring instrument 6 is pushed upwards under the action of the threads in the inner cavity of the fixing ring 51 located at the upper side and the threads at the lower part of the outer surface of the measuring instrument 6.
In summary, the specific embodiments thereof are as follows: when the measuring instrument 6 is communicated with the inner cavity of the conveying pipe 1 through the two fixing devices 5, the fixing ring 51 positioned on the upper side is driven to move downwards through the positioning device 8, the fixing ring 51 positioned on the upper side drives the connecting ball 42 to move downwards, and the sealing part 43 in the inner cavity of the first sealing groove 421 is stressed, so that a gap between the connecting ball 42 and the second fixing pipe 21 is sealed.
